Know Something About the
"Works" in the Watch You Buy
IF you open your watch and examine its
mechanism, you will find it consists substan
tially of two supporting plates, between which
is mounted a gearing of meshed wheels to
take care of the movement, recording time. This
is called the train, which we will speak of in our
next advertisement.
The lower supporting plate in a Waltham watch is the
foundation upon which every unit revolves and is fixed.
It is bored with minute holes to take the pivots, screws,
pinions, etc.
This lower plate is drilled and threaded by one of the most
exclusive and wonderful machines ever designed by the
genius of man - an exclusive Waltham invention from the
master-mind of Duane H. Church.
Many operations are accomplished with such methodical,
automatic regularity that one instinctively imagines that a
marvelous human brain guides the extraordinary opera
tions of this machine.
It makes every operation (and there are 141) with infinitesimal exactness
to the ten thousandth part of an inch -flawless, beautiful in its complex
simplicity-every plate a replica of every other plate, proving Waltham
standardization to be one of the miracles of American mechanical genius.
The plate of the foreign built watch is subject to the variations of hand
process. Made to variant sizes and models without precise relation to
the parts which they are to contain, which parts are made elsewhere in
many homes and small shops, by hand.
